The Source appeared in the middle of the Great Hall and stood there waiting for everyone's attention. Dumbledore stood up saying, "Leave this place now." The Source looked at him before laughing, "You can't make me leave, but don't worry I won't hurt many of your precious students. I just want the three I came for" He started to advance on the Gryffindor table.
Piper, Phoebe, Paige, and Dumbledore were the only people who knew it was the Source, so when he began to bear down on the Gryffindors, people naturally assumed Voldmort had sent him to kill Harry.
Harry saw the figure approaching, standing up he said, "So is Voldmort to afraid to come himself?" Ron and Hermonie also stood up, "If you want him you'll have to fight us." They warned.
The Source looked annoyed, these three fools were standing between him and his goal. Then he grinned, "Boy I'm not interested in this Voldmort person, I just want the Charmed Ones." He said as he through an energy-ball at Harry, Ron, and Hermonie to get them out of the way.
Throughout this confrontation, Piper, Phoebe, and Paige had been deciding what to do, but when they saw the energy-ball, Piper quickly froze the energy-ball at exactly the same time that Hermonie happened to put up her hands to shield her face. She looked at her hands, "Did I do that?" she wondered aloud.
Paige mentally pushed the energy-ball back toward the Source. Unfortunately she did so exactly when Harry waved his hand in the air trying to figure out what happened to the energy-ball.
The Source disappeared before the energy-ball hit him. He had done enough, the Charmed Ones would come to him now.
Gasps filled the hall as many people whispered, "They're the Charmed Ones, that Demon said so. Did you see them freeze that fire thing?"
Piper, Phoebe and Paige looked at each other wondering what do.
"Let's wait until after things have settled down a bit before talking to them." Piper suggested. Phoebe and Paige agreed.

Everyone slept in the Great Hall that night in case any other demon decided to venture into Hogwarts. Whispers filled the Great Hall until long after midnight. It was no use trying to talk to Harry, Ron, and Hermonie until tomorrow, they were in a state of shock.
